#include <windows.h>
#include <stdio.h>

int main() {
    SYSTEM_INFO si;
    
    GetNativeSystemInfo(&si);
        
    printf("Number of Logical Processors: %d\n", si.dwNumberOfProcessors);
    printf("Page size: %d Bytes\n", si.dwPageSize);
    printf("Active processor Mask: 0x%p\n", (PVOID)si.dwActiveProcessorMask);
    printf("Minimum application address: 0x%p\n", si.lpMinimumApplicationAddress);
    printf("Maximum application address: 0x%p\n", si.lpMaximumApplicationAddress);
    printf("Processor type: %u\n", si.dwProcessorType);

    printf("OEM ID: %u\n", si.dwOemId);

    char ch = getchar();

    return 0;
}




/*
